ROBERT HUGHES, OF VATERFORD, NEWT YORK.

HYDRANT.

SPECIFICATION forming part of Letters Patent No. 394,652, dated December18, 1888.

Application Bled August 7, 1888. Serial No. 282,142. 'No model.)

To all whom t may concern:

Be it-'known that I, ROBERT HUGHES, a citizen of the United States,residing at `Water ford, in the county of Saratoga and State of NewYork, have invented new and useful Improvements in Hydrants, of whichthe following is a specification.

YThis invention relates to improvements in hydrants of that class knownas tire-hy drants, and which in operation have a firehose connected totheir discharge-opening; and it consists in certain novel featureshereinafter described and claimed.

In the accompanying drawings, Figure l is a vertical section of thestand-pipe or casing of my hydrant, showing the interior mechanism inside elevation. Fig. 2 is a vertical section of the casing, the interiormechanism being removed. Fig. 3 is a horizontal section 011 the line c:1c of Fig. l. Fig. l is a iew similar to Fig. l, and showing the partsin a Fig. 5 is a rear view of the plunger, and Fig. 6 is a verticalsection on the line y y of Fig. 7. Fig. 7 is a detail view.

Referring to the drawings by letter, A designates the stand-pipe orcasing, of the usual construction, provided with an inlet-opening, B, inone side near its lower end and having 'a suitable discharge-openin g atits upper end.

On the upper side of the bottom of the casing I provide a drip-cup, C,having suitable apertures, D, in its side, and having an open bottomwhich registers with a vertical opening, E, in the bottom of the casing.

F designates my improved plunger, consisting of the plunger-head G,having' the diskvalve I-I secured to its front side and provided on itsrear side with the ribs or flanges I J, which are adapted to engage avertical rib, K, on the rear side ot' the casing, thereby guiding theplunger vertically7 in its up-and- The disk-valve H is provided on itsfront face with a packing-ring, L, and is adapted to close theinletfopening B, the packing-rino' ser ing to form awate'rtight jointwith the front side of the casing. The plunger-head is enlarged at itslower end and the flanges I are at the opposite sides or edges of thisenlarged portion and are adapted to engage the side edges of anenlargement,

` M, at the lower end of the rib K at th? lower side of the casing. Theiianges .I are provided at the upper end oi' the plunger-head, and thelower edges of said flanges are beveled outwardly and downwardly, so asto e11- gage the upper beveled edges ot' the enlargement M, and therebylimit the downward movement of the plunger-head.

The disk-valve His provided on its rear side at its center with a stud,N, which engages a circular opening, O, in the front side of theplunger-head, and is cushioned therein by means of a small rubber block,P, secured in the plunger-head.

Q Q designate triggers, which are arranged in sockets R, formed in theplunger-head, and depend from the lower end of the same, and are adaptedin the operation ot' the device to contact with a block, S, on thebottom of the casing, and thereby be forced upward in the sockets R. Theupper ends of the triggers Q are made wedge-shaped and act upon thewedges T, which are seated in recesses IY in the front face of theplunger-head and bear against the rear side of the disk-valve I'I. Bythis arrangement when the plunger is lowered the wedges T are forcedoutward, and, bearing against the disk-valve, cause it to bind firmlyagainst the front side of the easing, and thereby effeetually out offthe flow of the water.

In order to reduce friction between the wedges T and the triggers Q, Iprovide between their adjaeent surfaces the frictionrollers Y.

The plunger is provided with an rinterior screw-threaded opening, X,which is engaged by the operating screw-shaft Y, as shown.

Z designates a vertical stationary rod provided at its upper end with alaterally-projecting collar, a, swiveled on the upper end of theoperating-shaft- The said rod lies in a groove, b, in the side of theplunger-head and has pivoted to its lower end and at a suitable pointabove its lower end the link c and dog d. The dog d has its rear endpivoted to the upper end of a piston-rod, e, and the rear end of thelink c is pivoted to thesaid piston e, the said piston e having apiston-head, f, on its lower end, which is adapted to engage thedrip-cup C and prevent the flow of water through the saine. The frontend of the dog d has its upper edge provided with atongue,

will be readily understood.

g, and a recess, 71 in the rear of the said tongue, the front edge ofthe said dog being beveled downwardly and rearwardly, as shown. The saidtongue is adapted to engage a lateral pin, z', at the upper end of theplungerhead, and the front beveled end of the dog rides over the curvedupper -edgevof a guidestrip, j, formed on the side of the plungerheadand extending nearly the entire length of the same.

The construction and arrangement of the several parts of my hydrantbeing thus made* is rotated so as to raise the plunger, thereby removingthe disk-valve H from over the in- `let-opening and allowing the waterto enter the casing or stand-pipe, through `.which it will rise to thedischarge-opening at .theupiper end v.of the same yand ythence :pass`out through the hose. `Asthe plunger-head rises, the upper curved endof therguide-platej will .impinge against the front beveledend of thedogzdand raise-the said front end of said -dog, thereby lowering therear end of the dog .anddepressing the piston e, so as to drive theypiston-head j' into the drip-cup, closing the y sameand preventingthef1ow of the water therethrough, so thatthe water will be caused `torise positively th rough the casingor stand- .ripe- Vhenit is desired-to.cut off the flow of water, the operating-shaft isfrotated so astoAlower the plunger, thereby moving the valvedisk over the inlet-opening. As the plungerhead descends,the pin yz' on thev upperend of the samewill engage the tongue g of the dog (l, and thereby lower the front endof the said dog, consequently raising the pistone and withdrawing thepiston-head j' from the drip- ,cupyso that the water in the stand-pipeor casing will be` allowedto escape and be prevented from stagnating.

From vthe 4foregoing description, taken in connection with the annexeddrawings, it will beseen'that I have provided a simple and lefficientiire-hydrant,and the vadvantages of the same fare thought to be obvious.

.'Havin g thus described my invention, whatl claim, and .desire tosecure by Letters Patent, is*

1.2111 a i hydrant, the combination Iof :the

.casinghthe.plunger-head moving vertically in the casing and having inits front side a circular opening, O, and the recesses U, arranged onopposite sides of said opening, and provided in its bottom with thesockets R, the disk-valve having a stud engaging the open.- ing O, thewedges seated in the recesses U and bearingagainst fthe rear side of thediskvalve, and the triggers projecting through the sockets R and havingwedge-shaped upper ends bearing against the wedges in the recesses U, asset forth.

2. The combination of the. casing, the plunger-head moving vertically inthe casing and provided in its front face with the circularv opening O,and the recesses U on opposite sides of said opening, and having thesockets R in its bottom, the disk-Valve having a stud, N, .engagingtheopening O,the cushion iP, secured in .the plunger-.head and bearing `onsaid stud, the wedges V, seated .in the recesses AU and .bearing againstthe rear side of the disk-valve, the triggers proj ectinggthrough `thesockets R and `having wedge-shaped upper ends acting on the .wedges V,and the friction -rollers 4arranged between the Vsaid triggers andwedges, as set forth.

3. The combination ofthe casinghaving an inlet-opening and `provided onthe inner'face `of its rear side Withthe vertical guide-rib K,4having-an enlargement, M, at .its lower end,

and the vertically-movable :plunger carryingaidisk-valve adapted toclose the inlet-opening and `provided on vits rear side with the anges Jat its Tupper end, having beveled lower. edges adapted .to .contact withthe enlargement M, the plunger being furtheryprovided at its lowerendwith the flan gesl, adapted to engage the edges of the.enlargement M,
